PIPE AND TUBE.

Specification of Letters Patent.

Patented Doc. 2f), 1914.

Application filed March 6. 1914. Serial No. 822.923.

Ib au whom it may concern.'

Be it known that I, WALTER CONAN, a subject of the Kin of Great Britain, residing at Ard na ree, Dalkey, county of Dublin, Ireland, have invented certain new and useful Improvements in Pipes and Tubes, of which the following is a specification.

This invention proposes improved means for preventing the occurrence of air-locks and similar oistructions in pipes, or tubes, such as the feed pipes of hot water installations, the petrol supply pipes to the carbureters of motor curs, motor car radiator tubes, or other pipes tubes or conduits carrying or used for the passage of fluid or liquid; and the invention consists in forming the pipe or tube with a core so that the cross section of the openinr becomes annular or approximately so, spending upon the configuration of the core.

The core ma be solid or hollow, rigid or flexible, and o a suitable diameter to pass into the tube; the diameter of the core relatively to that of the tube being ad3usted as may be desirable or necessary according to the articular apilication of the invention. rlhe pipe or tu e and the corresponding core may however be extruded together, one within the other.

1t has been ascertained that it is possible to coil a pipe or tube, provided with a core as above described, into any desired shape or shapes, whether regular or not, and that even when arranged in the most complicated manner there is no tendency for an nir-lock or other obstruction to form when a fluid or liquid is passed through the pipe, said fluid or liquid flowin with perfect regularity from the exit cn of the pipe as soon as sufficient pressure has been attained to carry it over the highest point in the tube.

Pipes or tubes with cores may be manufactured in accordance with the invention of any cross sectional configuration required to suit any particular installation or circumstance, and the core may be concentric or eccentric to the tube and may also be single or multiple.

Several forms which the pipes or tubes constructed in accordance with this invention may take are illustrated by way of example in Figures 1 to 4 inclusive of the accompanying drawings wherein each form is shown in cross section. Fig. 5 is n diagrammatic cross section of a. device to illustrate the passage ol' a liquid or fluid from one container to another through a cored tube or pipe.

As will be sccn on reference to Fig. 1, the pipe a may be of the usual circular form and the core may be solid und ol a corresponding forui to lhat of the pipo and arranged within sanic so that an annular sVace is loft betwcen it and tho pipe. Or, tic coro l) may be cruciform in section as shown in Fig. :2. 'l'hc tube n, may be oi rectangular scction if' desired, and in such u case the coro l) may bc. of a corresponding scction. cithcr hollow or solid, or may be of' crnci form section. as illustrated in Figs. Il and l respectively.

The cored pipo or tube may be wound in any desired fashion and it is shown in Fig. 5 in the form of a simple helix, in which case the pipe a connects an open receptacle c with a closedreceptacle (Z. When it is desired to pass, say, a liquid from the receptacle c to the receptacle Il, for any purpose, it will be found on the liquid being.r placed or poured into the receptacle c that on suflicicntprcssure or headbcing obtained and notwithstanding that the receptacle (Z may be full of air or gas such as would resist thc flow of fluid through an ordinarily -constructed tube, said liquid will flow approximately down or around the one side of the core within thc. tubo while the air or gas within thc receptacle fl simultaneously escapes by wa v of the rem-.lining spacc between thc core and tube which is not filled with the liquid, thus totally eliminating any tendency to nn air-lock and ensuring a constant and uniform flow of" the li( nid. Thus, in the use of the pipe, there will lio a column of liquid flowing in one direction along the core, e. g., downwardly, and a column of nir or gus surronmling said column of liquid and flowing in nn opposite direction. c. g., upwardly, bctwccn the saine and thc inncr circumf'crcntial surface of' the pipe.

In addition to thc application above referred to, the invention may also be utilized in conncction with lulrolnctcrs and thermometers, water tube boilers, radiators and in fact in any case where a fluid or a li uid is to be conveyed from one point to anot ier, or where a liquid is required to be rapidly volatilized.

ein

What I claim is In combination, a liquid-conducting pipe and a core arranged therein and following the outline thereof, the core being longi- 5 tudinally continuous and co-eXtensive with said pipe and being spaced at all points ifrorn the inner circumferential surface of seid pipe and serving to deline, in conjunction With the pipe, a circumferentially and l0 longitudinally continuous liquid passage of generally annular cross-section, whereby in the use of the pipe e column of liquid substentielly iilling the pipe will descend in one direction along the surface of the core and any entrained gas or air will flow in un opposite direction in surrounding relation to seid column of liquid.

In testimony whereof I have hereunto setmy hand in presence of two subscribing WitA messes.
